Red, high strength, primerless threadlocker stick

Designed for high-strength permanent locking and sealing of threaded fasteners. Removable with heat.

The LOCTITE® 263 is a red, high strength, primerless threadlocker for permanently locking and sealing bolts, nuts and studs to prevent loosening due to vibration. It works on all metals without primer, including passive substrates such as stainless steel, aluminum and plated surfaces. Suitable for use on most oil-coated, 'as-received' fasteners without cleaning.
